Paraseal Saltwater (SW)
Verified by manufacturer over a year ago
Dual layer sheet waterproofing membrane for superior protection to below grade structures against the presence of brackish water.
Application
- A sheet applied waterproofing membrane specially designed for waterproofing applications in areas where saline, alkaline, acid, etc. conditions exist.
- Typically used in elevator pits, retaining walls, below grade waterproofing, tunnels and below footing slab.
Description
A multi-layer sheet membrane waterproofing system consisting of a self-sealing, expandable layer of bentonite laminated to an impermeable, high-density polyethylene (HDPE).
- Dual layer waterproofing system provides redundancy and added security to the builder and owner that water will not enter.
- Can be installed 24 hours after the concrete formwork has been removed, allowing for a faster construction schedule.
- Does not need to cure, so backfill can commence as soon as the sheet has been installed.
- Robust and can handle a variety of site conditions.
- The bentonite can expand up to 8 times its original thickness to stop water that may make it past the HDPE layer, providing a second layer of failsafe protection.
- The robust HDPE layer provides significant (180kg/m²) of puncture resistance to ensure damage doesn’t occur to the waterproofing membrane by careless trades.
- Chemically treated bentonite hydrates even in the presence of heavily salted/brackish water.
